MFC r312467:

Use SRCTOP-relative paths and .CURDIR with :H instead of ".." specified paths

This implifies pathing in make/displayed output

r264400:

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

r265836:

Remove last two NO_MAN= in the tree. In both of these cases, MAN= is
what is needed.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Only install manpages and html documentation in the ncurses/*w (wchar)
builds so that it is only installed once. This is consistent with the
existing decision to only install headers in the that case.

- When I introduce wide character enabled ncurses into base, all headers
are installed twice (once in non-widec version, onec in widec version).
Headers with widec enabled are compatible with non-widec version
for libraries. However, if you do a repeat build/install, the curses.h
is always overwritten. The reason is that headers and statics libraries
are installed with -S option to preserve their mtime if no actual changes,
which saves time when doing incremental builds. The curses.h is installed
by non-widec ncurses first, then by widec ncurses. So next time, it happens
again. You see something like this:

# pwd
/usr/src/lib/ncurses
# make -s installincludes INSTALL="install -v"
===> ncurses (installincludes)
install: curses.h -> /usr/include/curses.h
===> ncursesw (installincludes)
install: curses.h -> /usr/include/curses.h
# make -s installincludes INSTALL="install -v"
===> ncurses (installincludes)
install: curses.h -> /usr/include/curses.h
===> ncursesw (installincludes)
install: curses.h -> /usr/include/curses.h

The solution is to disable installing headers in non-widec version. Now
you see this:

# pwd
/usr/src/lib/ncurses
# make -s installincludes INSTALL="install -v"
===> ncurses (installincludes)
===> ncursesw (installincludes)
# make -s installincludes INSTALL="install -v"
===> ncurses (installincludes)
===> ncursesw (installincludes)

For form/panel/menu libraries, the headers are the same for both version.
To be consistent with ncurses, I also disable the installation in non-widec
version.

- style.Makefile(9) fix
- first line is $FreeBSD$
- Reorder special variables: DPADD, LPADD, CFLAGS
- Use = instead of += for variables that are initially empty
- Use space instead of tab after :
- Use one tab after =
- Use .SUFFIXES for section 3 manual page which simplifies Makefile a lot
- Use SHAREDIR instead of /usr/share
- Remove SRCDIR in INCS since we set .PATH properly
- Use plural in variable name when it stands for more that one source file
